It was in a thread a while back and I think it was 4lbs 4oz. Search it. In 1998 there was an Avalanche and an Avalanche LE in the line. both were 6000 series aluminum with integrated seat clamp probably very similar in weight. Without having the frame on the scale your never going to know for sure. Too many variables with or without water bottle boss bolts, BB cable guide, seat clamp?????
